Definition
| the process by which a cell divides into two new daughter cells |
|
|
Term
|
Definition
| The first stage of cell division. Division of the cell nucleus |
|
|
Term
|
Definition
| The second stage of cell division. Division of the cytoplasm |
|
|
Term
|
Definition
| one of two identical "sister" parts of a duplicated chromosome |
|
|
Term
|
Definition
| Each pair of chromatids is attached at the centromere, which is usually located near the middle of the chromatids, although some lie near the ends. |
|
|
Term
|
Definition
| an in-between period of growth between each cell division. The cell grows and replicates it's DNA and centrioles |
|
|
Term
|
Definition
| a cell grows, prepares for division, and divides to form two daughter cells, each which then begins the cycle again |
|
|
Term
|
Definition
| The chromatin condenses into chromosomes. The centrioles separate, and a spindle begins to form. The nuclear envelope breaks down. |
|
|
Term
|
Definition
| two tiny structures located in the cytoplasm near the nuclear envelope |
|
|
Term
|
Definition
| a fanlike microtubule structure that helps separate the chromosomes |
|
|
Term
|
Definition
| The chromosomes line up across the center of the cell. Each chromosome is connected to a spindle fiber at its centromere. |
|
|
Term
|
Definition
| The sister chromatids separate into individual chromosomes and are moved apart. |
|
|
Term
|
Definition
| The chromosomes gather at opposite ends of the cell and lose their distinct shapes. Two new nuclear envelopes will form. |

Term
|
Definition
| these cells do not respond to the signals that regulate the growth of most cells |
